Abstract

Long bean is the one of the most widely consumed vegetables both fresh and processed. The market demand for long beans is rising, but their production remains limited. This study aims to investigate how different concentrations of paclobutrazol and various types of nitrogen fertilizers affect the growth and yield of long bean plants. The research was conducted in Dander Village, Dander District, Bojonegoro Regency, East Java. The study employed a factorial Randomized Block Design (RBD) with two factors: the concentration of paclobutrazol (P0 = control, P1 = 150 ppm, P2 = 200 ppm, P3 = 250 ppm) and the type of nitrogen fertilizer (N0 = NPK control, N1 = Urea, N2 = ZA, N3 = KNO3). Variables to observed included plant length, number of leaves, flowering age, number of pods, pod weight, number of seeds, and fruit set. The results showed that the combination of 150 ppm paclobutrazol and KNO3 nitrogen fertilizer produced the best results in terms of the fastest flower emergence at 29 days after planting (HST) and the highest pod weight of long beans at 43.00 grams per plant. Keywords: Paclobutrazol, Various Nitrogen Fertilizers, Growth, Yield, Long Beans (Vigna sinensis L.)

Abstract

Shallot is a horticultural commodity that is always needed for consumption and has high economic value. However, shallot production in East Java has decreased due to the low quality and quantity of shallot seeds. This study aims to determine the effect of concentration and frequency of paclobutrazol application on the growth and yield of shallot. This research was conducted in Sambigede Village, Sumber Pucung Subdistrict, Malang Regency in January-May 2024. The research was arranged using a Split Plot Design with 3 replication. The main plots were paclobutrazol concentrations: 50 ppm, 100 ppm, 150 ppm, and 200 ppm. The subplots were the frequency of paclobutrazol application: 1 time, 2 times, and 3 times. The combination of paclobutrazol concentration of 100 ppm and application frequency of 1 time gave the best results in inhibiting the vegetative phase, increasing tuber dry weight per clump, harvest index, and chlorophyll content. The frequency of paclobutrazol application did not significantly affect the fresh weight of tubers per clump, fresh weight of tubers per plot and dry weight of tubers per plot, but paclobutrazol concentration of 100 ppm affected the fresh weight of tubers per clump. Keywords: Bulbs, Harvest, Paclobutrazol, Shallot, Vegetative.

Abstract

Sweet corn production in Indonesia is relatively low due to instability and many factors, including infestation of pests and diseases, inappropriate and inefficient cultivation techniques, and the varieties. Pruning the leaves below the cob and applying nitrogen fertilizer may improve yield. The aim of this research was to investigate the combined effect of leaf pruning and types of nitrogen fertilizer on the growth and yield of sweet corn plants. A plot experiment was performed in a Randomized Block Design with 2 factors, namely leaf pruning (no pruning, 1 leaf remaining, 2 leaves remaining, and 3 leaves remaining below the cob), and types of N fertilizer (Urea 4.5 g/plant, ZA fertilizer 9.6 g/plant, and KNO3 fertilizer 15.5 g/plant). Results showed that the best type of N source was KNO3 fertilizer with fresh weight of dehusked cobs (217.68 g), cob diameter (44.84mm), and sugar content (16.26%). Combination treatment of KNO3 fertilizer and the 3 leaves remaining provided the best results on the parameters of fresh weight of husked cobs (308.50 g), cob length (18.83 cm), weight of husked cobs (10.12 kg/plot), and yield of husked cobs (28.11 ton/ha). Keywords: Cultivation, Fertilizer, Nitrogen, Productivity, Sweet corn.

Abstract

Long bean production has decreased in Indonesia due to uncertain seasonal factors, such as long dry seasons and short rainy seasons. Long bean production has decreased due to inappropriate and optimal cultivation techniques. Several efforts can be made to overcome the problem of decreasing long bean productivity by fertilizing and applying growth regulators. The aim of this research is to understand the combined effect of KNO₃ fertilizer doses and paclobutrazol concentrations on the growth and yield of long bean plants. Thise research was conducted in Ketawang Village, Nganjuk, East Java. The research was a factorial experiment with Split Plot Design consisted of two treatment levels, namely KNO₃ fertilizer dose (0 g/plant, 8 g/plant, 10 g/plant and 12 g/plant) and paclobutrazol concentration (0 ppm, 150 ppm, 175 ppm and 200 ppm). The combination of 10 g/plant KNO₃ + 150 ppm paclobutrazol influences the growth and yield of long bean plants, however the application of KNO₃ fertilizer alone has no effect on the growth and yield of long bean plants. Keywords: Giberelin, Growth regulator, Harvest, Nutrient, Retardant.

High productivity and selling value greatly influence successful cultivation techniques. Red chili productivity in 2019 reached 8.62 tons/ha while its potential can reach 12-20 tons/ha. The factors that cause chili plant production to be less than optimal include low soil fertility and plant pests (OPT) caused by the lack of application and knowledge of farmers regarding GAP in cultivation activities. The objectives of community service activities through the Bertani Untuk Negeri (BUN) program are (1) to increase farmers' knowledge regarding good and correct cultivation techniques (2) to increase the application of SOPs based on GAP in chili plant cultivation activities, (3) to increase farmer productivity on their land. The activities carried out to achieve these objectives are by conducting field school activities for assisted farmers, the material provided is taken based on 5 problems that often arise in farmer cultivation activities, conducting direct assistance on farmer's land which allows students and farmers to transfer knowledge directly to farmers in cultivation activities on the land, conducting interviews, regular visits every week and inputting data related to activities, problems and matters related to cultivation activities on land owned by assisted farmers. To measure the level of success of the BUN program, a pretest was carried out before the program was run and a posttest after the program was implemented as well as taking productivity data before and after the program. After measuring the level of improvement, the results showed that farmers experienced an increase in (1) knowledge, of the 5 farmers, 1 farmer experienced an increase of 10%, 3 farmers 5% and 1 farmer 0%, (2) cultivation SOPs for the 5 assisted farmers experienced an increase of 23%, 25%, 29%, 35%, 40%, (3) productivity increase for the 5 farmers, 2 farmers experienced an increase and 3 farmers experienced a decrease and the productivity target of 7 tons/ha had not been achieved by the 5 assisted farmers. Keywords: GAP; chili cultivation; improvement; farmer field school.
